This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
In servlet code, can we register a piece of information with the underlying JVM, and retrieve it later (by another web module servlet)?
If a servlet in one web module registered some information with JVM, then a servlet in another web module can read that information out during init() time, and know the existence of the former servlet. The two servlets can even be the same class but deployed in two web modules.
Can we do that in our code? Or it is generally impossible because the servlet container will disable such communication?
